Overview
The Extech Heavy Duty Light Meter enhances accuracy by selecting one of four lighting types: tungsten/daylight, fluorescent, sodium, or mercury. The meter utilizes a precision diode and color correction filter and adjusts for cosine and color-corrected measurements. The microprocessor assures maximum accuracy through an Fc range of 200.0, 2000, and 5000Fc and a lux range of 2000, 20,000, and 50,000 lux.

Data Storage
The built-in RS232 serial interface provides a connection with the optional Windows Data Acquisition Software, which enables users to display and capture readings on a PC and set time intervals and alarms. The battery-operated datalogger module stores over 8000 readings for later transfer to a PC.

Sargassum Surge: How Seaweed is Transforming our Oceans and Coastal Ecosystems

Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.

Great Lakes Research Center: Designing Targeted Monitoring Solutions

According to the National Oceanic and Atmospheric Administration ( NOAA ), the Great Lakes have more miles of coastline than the contiguous Atlantic and Pacific coasts combined and contain 20 percent of the world's freshwater, making it a critical region to protect and conserve. Continuous monitoring and data-informed resource management are key components of managing waters in the region. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs and deploys monitoring platforms throughout the Great Lakes. With a background in environmental engineering, Henderson enjoyed the challenge of creating systems and making them work to obtain difficult, remote measurements.

Monitoring Meadowbrook Creek: Real-Time Data Collection in an Urban Creek

Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing. [caption id="attachment_39339" align="alignnone" width="940"] An overview of the Fellows Ave monitoring station along Meadowbrook Creek.
